NESP TWQ Project 5.9 - Gully remediation effectiveness, 2019-2020 (CSIRO)

Updated: 2026-06-25

There is significant Government investment in water quality improvement focused on reducing gully erosion (~$50M), however, there is limited measured data to demonstrate the effectiveness of the remediation approaches. This project is collected land condition, terrain and water quality data from five gully remediation trial sites in the Burdekin catchment. The data demonstrated whether the on-ground investment programs are actually improving measured water quality, and quantified the cost-effectiveness of the various approaches. The measured field data was extrapolated using Lidar, supporting the prioritisation and evaluation of future remediation sites over larger (whole of property) scales. Communication products were developed to provide the evidence needed to increase landholder engagement in remediation programs that are focused on improving water quality runoff to the GBR. This project is a continuation of NESP TWQ Round 2 - Project 2.1.4.
